The litter is composed of vermicompost and adult, juvenile and egg compost worms.
They eat the decomposing matter several times to make natural fertilizer, the "vermicompost".

Their population is regulated according to the quantity and quality of waste. They associate with other living beings, such as woodlice and many other organisms that cannot necessarily be seen with the naked eye.
It's very alive.

Their digestive system contains enzymes that make vermicompost directly assimilable by plants.

You can put it directly on bare roots.
